f0 all whom it may concern:

'Be it known that I, WILLIAM H. JACKSON, a citizen of the United States,and a resident of Palisade, Bergen county, New Jersey, have inventedcertain new and useful Improvements "in Time-Recording Ap paratus, ofwhich the following is a specification.

My invention relates to time recording apparatus; and, while it may beembodied in constructions adapted for various purposes, it is moreparticularly applicable to apparatus for recording the times of workmento facilitate computing wages and the labor costs of work done.-

The object of the invention is to provide a time recording apparatuscapable of registering the individual records of numerous workmen, andwhich is at the same time simple in construction and positive in action,and proof against falsification of the records produced thereby; also toprovide a machine adapted to register the times of workmen duringperiods of various lengths, and to record the units of time spent byeach workman on each piece of work during said periods as well as thetotal time of each workman; also to produce a machine which willautomatically adjust itself for the different working periods; also toproduce a time recording apparatus in which a number of recorders arecontrolled from a central station, as by a single clock mechanism; Theseand other objects of the invention will in part be obvious and in partbe more fully explained in the following description.

The invention consists in the novel parts, combinations, features ofconstruction, and improvements herein shown and described.

The accompanying drawings, which are referred to herein and form a parthereof, illustrate one embodiment of the invention, the same serving inconnection with the description herein to explain the principles of theinvention.

Of the drawings: Figure l is a rear elevation of one embodiment of therecording mechanism forming'one feature of .my invention, the rear partof the casing being broken away to expose the mechanism; F1 2 is anenlarged perspective view of a detail of the mechanism; Fig. 3 is a planview of another detail; Figs. 4 and 5 are, respec-. tively a verticalsection and rear elevation of another detail; Fig. 6 is a side elevationillustrating a plurality of recording mechanisms and a clock controlledmechanism for operating the same; and Fig. 7 is a face view of a recordsheet or card adapted to be used in connection with my recordingmechanism. Fig. 8 is a side elevation of the card receiver detached.

A time recording apparatus constructed in accordance with certainfeatures of my invention comprises in combination, a suitable casing, areceiver for the record sheet or card which while inclosed in the casingis freely accessible from the exterior thereof for the reception ofindividual time cards, a marking device for the time card, mechanism forproducing a relative movement between said receiving and markingmembers,

said mechanism being positive in action dur-" ing a predetermined periodof operation whereby the movable member can be neither advanced norretarded independently of said mechanism during said period.

In accordance with another feature of my invention, means are providedfor automatically releasing the said mechanism at the end of the'saidpredetermined period to permit the movable member to be returned to astarting position for the next period.

anisms during the recording periods but also to automatically controlthe said periods.

These and other features of the invention will be more fully explainedin connection with-the particular embodiment illustrated.

Referring now in detail to the embodiment of "the invention illustratedin the drawings, each of the recordin mechanisms, herein referred to asthe recor er, comprises a casing 1 which incloses the mechanism and isnormally closed and locked in any In accordance with another feature ofmy desired manner, not shown. As shown, the mechanism contained withinthe casing includes a card receiver, consisting of a bar 2 having a pairof arms 3 and 4.- fixed at the opposite ends thereof and arranged in aslot 5 in the casing, said slot being accessible from the exterior, asshown in Fig. 6. While either this card receiving member or the cardmarking member, hereinafter described, may be moved with relation to theother, in the embodiment illustrated the marking member is stationaryand the card receiving member is intermittently moved with relationthereto, the movements being efiected at predetermined intervals andbeing of a predetermined length to correspond to the minimum units oftime which it is desired to record.

In the construction shown the mechanism for intermittently moving thecard receiver is as follows: The bar 2 of the card receiving member isprovided with rack teeth and normally meshes with a gear 6, which isloosely ournaled on a shaft 7. This shaft 7 is loosely journaled at oneend in a sleeve 8 rotatablymounted in a bearing formed in the framemember 9. Fixed to the inner end ofthe sleeve 8 is a spring 10, theother end of which is fixed to a gear 11 fixed on the shaft 7. The outerend 12 of the sleeve 8 is adapted to receive a key, which may beinserted through the opening 13 in the casing, as required to wind upthe spring, the sleeve being provided with a; ratchet 14 which isengaged by a detent 15 to retain the spring in its wound up condition.

The movement of the gear 11 under the influence of the spring iscontrolled by an escapement mechanism constructed as follows: Anescapement wheel 16 is fixed on a shaft 17, which is geared with thewheel 11 through apinion 18 and intermediate gears on a shaft 19. Anescapement rocker 20 is pivotally mounted above the escape wheel 16, andis provided with a fixed pawlarm 21 and a pivoted paw-larm 22. Therocker 20 is normally held with the fixed pawl in one of the teeth ofthe escapement wheel bya spring 23. The loose pawl is normally held inits retracted position opposite the succeedin tooth of the escapementwheel by any suit-able means, such as the spring 24. The rocker 20 maybe operated in various ways to permit the escapement wheel to advanceone tooth or step at a time under the influence of the spring 10. ,Asshown, the rocker 20 carries the armature 25 of an electromagnet 26,which is normally energized by aclock controlled electric circuit, aswill be presently explained. It will be seen that when'the armature 25is lifted by the magnet against the force of the spring 23, the fixeddog 21 will be moved out of the tooth of the esca ement wheel 16, andthe pivoted dog 22 wi 1 be simultaneously moved to engage the fixed dogor arm 21 by a spring 29. NVhen the pivoted dog arm 22 has been advancedby the spring 10 through the action of the escapement wheel 16, said arm22 will engage the latch 28 and release the arm 21, thus allowing therocker to assume its normal position under the in-' fiuence of thespring 23. It will be seen that this escapement mechanism is positive inaction. That is to say, the mechanism connected therewith is normallylocked by the rigid dog so that it cannot be moved in either directionand can only adyance one step at a time, when the recorder is actuated,and the rocker cannot return to its normal position until the mechanismhas advanced the distance permitted by the free movement of the pivoteddog arm 22.

In order that the movements of the .wheel 11 under the control of theescapement may be transmitted to the card receiver, as desired,

a clutch member 30 is s lined on the shaft 7- into and out of enso thatit may be mov gagement with a corresponding clutch member formed on thegear 6. So far as certain features of the invention are concerned, theclutch member 30may be operated in any suitable way to connect the gear6with the shaft 7 so as to start the movements of the card receiver andthus begin a recording period, and likewise the clutch may be operatedin any suitable way to stop the movement of the card receiver and thusend the recording period. In accordance with one feature of theinvention, moreover, the clutch is operated automatically both toconnect the escapement control mechanism with the card receiver and todisconnect or release said mechanism at: the end of a predeterminedrecording period. While this automatic mechanism for controlling theclutch may be constructed in various ways, as shown, the clutch 30 iscontrolled by a lever 31 fulcrumed on the gear 6 and adapted to beengaged and moved by certain devices normally fixed on the frame.

When the card receiving member is in the starting position, the outerend of the lever is normally restrained from movement under theinfluence of the spring by a catch 35 pivotally mounted on the arm 33and held in position to engage the slide 32 by a spring 36. This latch35 may be actuated to release the slide 32 in various ways. In theembodiment illustrated the catch 35 carries the armature 37 of anelectromagnet- 38, which is energized so as to release the arm 32, whenit is desired to start a recording period. One means for energizing thisma et will be presently explained. It follows from this constructionthat when the -ma et 38 1s energized so as to release the slide 32, thespring 34 will operate the clutch 30 to connect the wheel 6 with theshaft 7 The magnet 26 being energized intermittently, the card receiverwill be advanced step by step until the clutch 30 is actuated to releasethe escapement control mechanism from the card receiver. In theconstruction shown this releasing operation is effected by means of anarm 39, having at its end a cam arranged to engage the outer end of thelever 31 and move it so as to disengage the clutch 30 from the wheel 6.Any suitable mechanism may be providedto return the card receiver, whenthe driving mechanism is thus released. In the construction shown theweight of the card receiver is utilized for thispurpose. When the cardreceiver returns to the position from which it started,-the lever 31'will again engage the slide 32, which in the meantime has been returnedto its normal position by a cam 40 on the wheel 6, which dur-' ing theupward movement of the card receiver engages a suitable projection 32 onthe slide 32. Preferably and as shown, the slide 32 is provided with aslot 32 (see Fig. 3), which engagesthe end of the lever and acts as acam to move it so as to cause the clutch 30 to engage a correspondin andnormally fixed clutch member on the ub of the arm 33, the card receiverbeing thereby locked in its starting position until the magnet 38 isagain properly energized. It will be seen that by reason of thisconstruction the clutch 30 cannot be reengaged with the wheel 6 so as tostart the card receiver until the latter is returned to its startingposition.

In order that the starting and stopping positions of the card receivingmember may be varied so as to control the beginning and end and theduration of the recording period, both the arms 33 and 39 are adjustablymounted on the frame so that the clutch lever controlling membersthereon can be moved circumferen'tially or in the path of the free endof the clutch controlling ever 31. To this end the arm 33 is providedwith a sleeve, rotatably mounted in the fixed bearing 41 and providedwith a threaded stem 42, havin a thumb nut 43, the hub of the arm 39 Esnaled on the sleeve of the arm 33 and being loosely jourtween the hub ofthat arm and the bearing 41. It follows from this construction that whenthe nut 43 is loosened, both the arms 33 and 39 may be set in desiredpositions and then secured in such positions by again registering therecording marks on the cards carried by the receiver. Preferably and asshown, however, a perforating device is used for this purpose. Thedetails of this device in the embodiment herein illustrated are shown inFigs. 4 and 5. As here shown, a punch 44 is arranged on one side of theslot 5, in which the card receiver moves, and a die 45 on the other sideof said slot. The punch may be operated in various ways. As shown, it ismounted in a block 46 set in the front wall of the casing 1, which blockalso carries a punch operating lever 47, having a handle 48'. The punchis normally retained in retracted position by a spring 49. It will beseen that by de )ISS- ing the handle 48, the punch will be riven intothe die through the card so as to form a perforation in the latter.Preferably, suitable means are provided whereby each operation of thepunch is caused to sound a bell. As shown, a suitable electric bell 50is arranged within the casing 1, one branch 51 of the circuit beingconnected with the frame, and the other 52 being insulated from theframe and arranged to be engaged by a contact piece 53 carried by theoperating lever 48, as shown in Fig. 4.

So far as certain features of my invention are concerned, the magnets 26and 38 may be energized in any suitable way, the latter magnet beingenergized either automatically or by a hand controlled switch. Inaccordance with one feature of my invention, however, both thesemagnetsare automatically energized by clock controlled switches. In accordancewith one embodiment of this feature of the invention, moreover, a singleclock controlled mechanism is arranged to control both magnets, andpreferably, also, to control the magnets of a plurality of recorders bya single system of wiring, in-

volving the provision of a single electric wires 59 and 60 with themagnet 38, so that any electric circuitwhich is established through thewires 55 and 56 will pass through both magnets. The two magnets 26 and38 are, however, so constructed that one will only respond to onecharacter of electric current, and the other will correspond only to anelectric current of ,flows in one direction through the magnet,

the armature will be attracted; and when it fiows'in the otherdirection, the armature will be repelled. In the same way, the armature37 of the magnet 38 is a permanent magnet but this armature is soarranged that it will not be attracted when the cur-" rent flows in sucha direction as to attract the armature 25 but, will be attracted whenthe .current flows in the opposite direction. It will be seen thereforethat in order properly to operate and control the several recorders, itis only necessary to momentarily energize the wires 55 and 56 by acurrent flowing inthe 'proper direction to render the magnets 26operative at the required predetermined intervals corresponding to theminimum units of time which it is desired to record and to-momentarilyenergize the wires 55 and 56 by a current flowing in the oppositedirect-ion at the times when it is desired'to start the recording,operations. For example, if it is desired to start the recordingoperation at 7 oclock in the morning andito record ten minute intervalsof time, the clock controlled mechanism will be arranged to momentarilyenergize the wires 55 and 56 once every ten minutes by a current flowingin one direction, and" to energize the said wires by a current flowingin the opposite direction at 7 oclock in the morning. If it is desiredto have more than one recording period during each day, the wires 55 and56 will be energized with the reverse current at the beginning of eachdesiredperiod, in any case the several recorders being adjusted so as toautomatically stop the recording periods at the desired times. Forexample, the recording operations may be started at 7 oclock in themorning, automatically stopped at 12 noon, automatically started againat 1 oclock, automatically stopped at- 6 ocl'ock, and automaticallystarted again immediately thereafter, and then automatically stoppedbefore 7 oclock in the morning or at any desired time between 6 oclockatnight and 7 of the following morning. In the embodiment illustratedthe clock controlled mechanism for thus momentarily energizing thecircuit wires 55 and 56 is constructed as follows:

A wheel 61 is connected, as by a shaft 62,

trolled switch 72 to momentari with twelve pins 63, each of which isadapted to engage one end of a spring controlled lever 64. The oppositeend of the lever 64 is arranged to actuate a spring controlled switch 65adapted to make and break a circuit including the wires 66 and 67,respectively connected with the wires 55 and 56 and including a battery68 tending to send the current in the direction of the arrow. As shown,the switch '65 is so arranged that when the lever'64 is moved by each ofthe pins 63, the circuit will not be closed; but when the lever isreleased -by the pins, it will be moved by its spring so as tomomentarily close the circuit. It will be seen therefore that theeffectof the wheels 64 is to energize the wires 56 by the current from thebattery 68 once every ten minutes' Geared to the wheel 63 so as to makea revolution once every twenty-four hours is a wheel 69, which isprovided with any desired number of perforations in which may 7 beplaced in any desired relation to each other one or more pins 7 0. Thesepins operate on a spring pressed lever 71 in the same manner that thepins 63 operate on the lever 64, and the lever 71 operates a spring conyclose a circuit through the wires 55 and 56, which include a battery 73adapted to energize said wires with a current flowing in the directionopposite to that of the battery 68. It will be seen that by suitablyadjusting the pins 7 O in the wheel 69, the electric circuit may beenergized so as to start the recorders at any desired predetermined timeor times.

It will be obvious that, so far as some features of my invention areconcerned and if desired, the'ma 'nets 26 and 38 may be connected byentirely independent circuits with the two switches 65 and 72, saidseparate circuits being energized by suitable batteries or other sourcesof electric energy.

While various forms of record sheet or time card may be employed inconnection wlth the construction shown, a preferred form of. cardadapted to be used in connection with my recorders is illustrated inFig. 7. As here shown, the card is provided at the top with suitabledata, including the name of the workman, the department in which heisemployed, the date, the number of the card or workman, and the rate atwhich he is paid. Below these are several verticah columns, one for thenumbers of the various jobs in which he is em loyed, another for thecharacterof the WOI{ done, another for the total amount of work devotedto each job, and finally a column in WhlCh the time records are formed.The latt er column is divided first by horizontal lines nto spacesrepresenting the hours of a work ng period, and these spaces aresubdivided by horizontal lines into the minimum periods of time to berecorded, 6. 9., ten

minute intervals, which are. preferably designated both by theminutes ofthe hour and also by the-successive numbers of the units in the entireworking period. The lines designating the units oftime are graduated tocorrespond with the successive movementswill indicate the time or numberof units of work devoted to any particular 'ob. In like manner the spacebetween the rst and the last marks on the card, as indicated by thenumbers of the units, will represent the total time worked by theworkman during the working period represented by the card. If there isan intermission or recess during the workin period represented by thecard, the units 0 working time corresponding thereto will be left blankin the column of unit members. For example, if the period represented bythe card is the entire day from 7 in the morning until 6 at night andthere is a recess of a half hour from 12.30 to 1, the spaces reresenting the units between 12.30 and l willbe left blank in the columnrepresenting the units of work, the calculation of the time spent on thejob in hand during the noon recess and the total time of the workman forthe day being thereby facilitated.

In order to make a record on my recorder, all that is necessary-to do isfor the workman to insert the card in the. card receiver through theslot 5 and press the handle 48. If it should happen that the magnet beenergized while a record is being ma e, so that the card receiver is notfree to move when the escapement rocker is moved and released by themagnet, the said rocker will be retained in its abnormal position by thelatch 28 until the card is removed and the receiver thereby liberated.Thereupon the card receiver will move under the influence of the spring10 so that the pivoted dog 22 will advance and release the catch 28 andthus allow the escapement rocker to return to its normal position. If itwere not for the presence of the catch 28, it will be seen that if thecard receiver were prevented from moving, when the magnet 26 isenergized, the roc er would return to its normal position and the rigiddog 21 would return into the same tooth of the .escapement wheel fromwhich it had been withdrawn so that the card receiver would not beproperly advanced. With the construction shown .it will be necessaryinorder to prevent the advance of the receiver for each operation of themagnet 26 to hold the card receiver against the action of the spring 28during the entire period between the two successive operations of themagnet.

It obviously would be impossible for a workman to'do this withoutattracting attention unless he could in some way insert something intothe slot 5 which would prevent -the movement of the card receiver. Thiscould not be done without danger of detection but in order to prevent sofar as possible the operation of the machine being thus interfered with,I preferably provide means for closing the slot 5 above and be-' low thecard receiver, this means also makingit impossible to insert a card inthe slot except at the right point to-properly enter it in the cardreceiver. As shown, this means consists of a flexible strip 74 securedatone end to the upper arm 3 of the receiver and at the other end to aspring drum 75 mounted in the casing 1 adjacent to the.

upper end of the slot 5. A similar stri 76 may besecured to the lowerarm 4 o the card receiver and wound on a similar drum 77 mounted in thecasing at the lower end of the slot.

It will be understood that the springs 10 of the several recorders willbe rewound at suitable intervals by the person in charge of therecording apparatus, this being done by a suitable key adapted to beinserted through the opening 13 in the casing so as to engage thesuitably formed end 12 of the sleeve 8 to which one end of the spring 10is secured.

I may say in general that my invention in its broader aspects is notlimited to the particular constructions and arrangements shown nor toany particular construction by which it has been or may be carried intoeffect, as many changes may be made in the details of the constructionWithout departing from the main principles of the invention and withoutsacrificing its chief advantages.
